The Doctor stood by the controls to the TARDIS, with Mel, his trial was over and The Doctor knew it was time for them to part ways.
"But how can I go back to living a normal life after seeing all this?" Mel angrily asks.
"I'm sorry Mel but" The doctor was interrupted as the TARDIS violently shook, then it stopped. "According to these we've stopped, we're floating in space in an asteroid belt near the ruins of the Library, it's a whole planet that's a library" The doctor opened the door to the TARDIS and was shocked, there a security droid floating in space.
"What's that Doctor?" Mel asked
"It's a security droid from the Library, it's past the range where the AI can control it" The Doctor explained
"Doctor there's something carved into the side" Mel pointed out "What's it say?"
"Well, quit obviously it says" The doctor said turning it over "Hello Sweetie"
